This chapter describes how to operate the 2109 Model F16 and includes the
following information:
v "Turning on and off the 2109 Model F16"
v "Interpreting LED activity"
v "Interpreting POST" on page 19
v "Maintaining the switch" on page 20
To turn on the 2109 Model F16, connect one or both of the power supplies to a
power source, then flip the ac power switch to "I".
To turn off the switch, flip the ac switch for both power supplies to "O".
Note: When you remove all power from the switch, a system reset is triggered.
When you restore the power, all devices are returned to the initial state, and
the switch runs a POST, a one-minute system check.
You can determine system activity and status by monitoring the activity of the LEDs
on the switch.
Note: The LEDs might flash green, orange, or yellow during a POST. This is
normal and does not indicate a problem unless the LEDs do not return to a
normal pattern after a POST completes.
The 2109 Model F16 has the following LEDs:
Port Status LED
This front panel LED indicates the status of each port. There are 16 port
status LEDs, located above and to the left of each port.
Port Speed LED
This front panel LED indicates the speed of each port. There are 16 port
speed LEDs, located above and to the right of each port.
Switch Status LED
This front panel LED indicates whether the switch is on and has
successfully started. There is one switch status LED, located below the
serial port.
Power Supply LED
This back panel LED indicates the status of each power supply. There are
two power supply LEDs, one on each power supply.
Switch Status LED
This back panel LED indicates whether the switch is on and has
successfully started, or is running diagnostics. There is one switch status
LED, located in the center of the back panel.
